These planters are made of 3mm thick aluminum as standard, although they can also be produced in 4-5mm. Aluminum is light, strong, durable and resistant to corrosion. The top edge of all planters is reversed twice, which gives them a strong and timeless appearance. All Aluminum planters are equipped with 15mm high feet, so the planter is raised slightly off the ground. Once constructed the planters are powder coated with a strong adhesive primer and finished with a coloured coating. Wheels can be added as optional extras. The Sydney shape is round.
